MEMOLUB® EPS
Single-Point Lubricator

The MEMOLUBÂ® EPS is an externally powered electromechanical lubricator that can be installed on a single lube point or coupled with a progressive distribution valve to lubricate from 2 to 12 points. This model requires an external 24VDC power source.

The MEMOLUBÂ® EPS lubricator automatically delivers a small, precise amount of lubricant at regular intervals for an continuous supply of fresh lubricant directly to your lube point. Prevents over and under lubrication problems related to manual lubrication.

120, 240 or 480cc lubricant capacity

350psi max output pressure from start to finish

Use with Oil or Grease (up to NLGI #2)

Remote mount up to 40 feet from the lube point

Use in intermittently used applications

Memolub EPS - Pillow Block Bearing

All MEMOLUBÂ® EPS models use the same motor base assembly, making it easy to convert from one lubricant capacity to another by simply purchasing a low cost transparent housing kit.

Connecting Power to the EPS

The MEMOLUBÂ® EPS is supplied with a 12" wire lead that is connected to an external power source. A constant 24VDC power is supplied during periods of machine operation and will continue to follow the program until power is removed. When initial power is supplied to the MEMOLUBÂ® EPS lubricator it will cycle once and then follow the preset MEMO program. When power is turned off the lubrication cycle stops until power is reestablished.

Programming the MEMO System for use with the MEMOLUBÂ® EPS

The MEMOLUBÂ® EPS lubricant output is programmed using the simple MEMO system. It consists of a brass MEMO fitting, a black plastic timing-ring holder, and three plastic timing rings (one white, one red, and one black). The MEMO can be programmed to control both the frequency of lube cycles and the volume of lubricant discharged. Once the MEMO is programmed and installed any MEMOLUBÂ® EPS lubricator will recognize the settings.

Basic Frequency Settings

There are 7 basic frequency settings that are suitable for most industrial applications. They are programmed by installing one or a combination of the three colored timing rings into the ring holder attached to the brass fitting. When you screw the MEMOLUBÂ® lubricator onto the brass fitting, the timing rings depress the switches on the bottom of the lubricator. This activates the lubricator program.

Note: The "Months to Empty" is based on continuous use of the MEMOLUBÂ® EPS lubricator. The lubricant cartridge will last longer with intermittent use.

Adjusting the Volume of Lubricant

Included in the MEMO kit is eight spacer washers for adjusting the amount of lubricant discharged per lube cycle. Installing one, or a combination of all eight washers, into the brass MEMO fitting will limit the stroke length of the piston inside the lubricator.

Founded in June of 1986 primarily as a supplier of machine tools to Boeing, Electroimpact has positioned itself as the premier supplier of automated equipment to the worldwide aircraft industry and the largest integrator of aircraft assembly lines in the world.

Issue:

Electroimpact makes very specialized automated equipment. One such piece of equipment is this Wing Panel Machine which fully fastens airplane wings from start to finish at an astonishing rate of speed. It utilizes servo controls and electromagnetic riveting (EMR) technology to install 12 slug rivets per minute, and 8 lock bolts and collars per minute. Process tools on this equipment shuttle into position at speeds up to 2m/sec to drill, rivet, seal, and fasten wing panels into place.
A lot of parts moving simultaneously at high rates of speed means frequent and consistent lubrication is necessary to ensure smooth and uninterrupted operation. Manual lubrication was quite an undertaking to ask of the end user with so many points. Electroimpact first considered using larger Lincoln-type systems but the equipment moves along 3 axis, making it very difficult (if not impossible) to run lines to all service points from one central location.

Solution:

Electroimpact decided to employ EPS-24VDC PLC-controlled lubricators to lubricate the more than 50 lube points on this piece of equipment. The (relatively) small profile of the MEMOLUB and its mounting versatility made the system ideal for installing in limited/confined areas along the equipment. A mixture of 12-point, 8-point, and 4-point systems are used to service the slides, racks (on rack-and-pinion system), rollers, and worm gears on this massive piece of equipment.

Results:

Our MEMOLUB systems have made their way into the facilities of Airbus, Boeing, Spirit Aerospace, Vought, Northrop-Grumman, Israeli Aircraft Industries, and Xiâ€™an Aircraft of China among others by way of these highly specialized pieces of equipment. Some, like Boeing, had already been longtime customers of ours so they were familiar with the operation and maintenance of the systems. This project only served to open their eyes to more application possibilities.

Worth Mentioning:

Electro-Impact is an engineer-driven company and like many other customers of ours, required engineer drawings of our products to incorporate into their own machine designs. PLI has been able to deliver both 2D CAD and 3D STEP files to meet our customerâ€™s needs.
